umask [-S] [mask]
Display or set the file permission creation mask,
or umask (see umask(2)). If the -S option is used,
the mask displayed or set is symbolic, otherwise it
is an octal number.
Symbolic masks are like those used by chmod(1):
[ugoa]{{=+-}{rwx}*}+[,...]
in which the first group of characters is the who
part, the second group is the op part, and the last
group is the perm part. The who part specifies
which part of the umask is to be modified. The
letters mean:
u the user permissions
g the group permissions
o the other permissions (non-user,
non-group)
a all permissions (user, group and
other)
The op part indicates how the who permissions are
to be modified:
= set
+ added to
- removed from
The perm part specifies which permissions are to be
set, added or removed:
r read permission
w write permission
x execute permission
When symbolic masks are used, they describe what
permissions may be made available (as opposed to
octal masks in which a set bit means the corre­
sponding bit is to be cleared). Example:
`ug=rwx,o=' sets the mask so files will not be
readable, writable or executable by `others', and
is equivalent (on most systems) to the octal mask
`07'.
